Abstract: The present paper highlights the dominance, diversity and species richness of tree species along an altitudinal gradient of Mandakini catchment of Garhwal Himalaya. A total number of six forest stands were selected along an altitudinal gradient of Mandakini catchment. The study revealed that Density (trees/ha) and Total basal area (m2/ha) values of the selected stands ranged between 2084 and 600 trees/ha and 53.44 -29.36 m2/ha.
Maximum density 2084 trees/ha recorded for the forest stand IV and minimum 600 trees/ha for stand VI of Mandakini catchment. All the selected forest stands of the catchment area could be designated as broad-leaved mixed temperate forest. Rhododendron arborium is the common species in all the selected stands of the catchment except the forest stands III and Stand VI. Shannon-Wiener diversity index ranged between 1.16 and 1.66. Concentration of dominance showed reverse trend to diversity index. Heighest number of tree species (6) was recorded in forest stand V and I. Stand III and VI are the most similar sites of the study area.

Keywords: Acacia catechu, Heartwood, Katha and cutch yield
Abstract: Acacia catechu Willd is valuable tree found in sub Himalayan tract to the Indus, eastward to Assam and throughout the peninsular in the drier regions ascending up to 900m and sometimes found at 1200m amsl. Heart wood of Acacia catechu (khair) is used for extraction of katha and cutch. To evaluate the losses during storage and how losses cna be minimized, khair wood were kept in three different storage conditions viz. shade, shade with end bee wax coating and some blocks of wood were kept in open. To see the effect of heartwood thickness on the yield of katha, the heart wood was converted into small chips having four thicknesses. The maximum yield of katha was obtained from blocks coated with end bee wax and minimum in blocks kept in the open, as moisture content in the heartwood facilitates the extraction. Maximum katha yield was obtained in first month of storage and minimum in fifth month of storage. Katha yield also decreased with increase in chips thickness. The time of extraction is also reduced in case of lesser thickness due to quicker imbibitions of water. However, yield of cutch percentage is not affected by moisture content in the wood. Maximum cutch yeild was obtained in wood blocks, kept in shade followed by blocks end coated with bee wax and minimum in open stored wood.

Abstract: Ten half-sib progenies of Albizzia lebbeck belonging to different places of Allahabad regions were sown in glasshouse and field condition with a view to assess the impact of two different environments on the expression of genetic diversity using non-hierarchial Euclidean cluster analysis. Superior tree progenies were grouped into four clusters under glasshouse as well as in field atmosphere. Families of plus tree S9 and S10 formed one cluster both under glasshouse and field back ground. Inter cluster distance was found to be highest between cluster IV and II (59.06) under green house whereas, under field condition cluster III and I showed maximum (51.80) inter cluster distance. Within a cluster showed low intra-cluster distance (<1.681), under both teh environments, revealing their genetic closeness. Leaf area followed by seedling height contributed maximum to the total divergence and played a predominant role in creating the genetic diversity.

Abstract: About 80% areas of common pasturelands in arid and semi-arid tract of Rajasthan is extremely low productive because of excessive grazing, soil erosion and land degradation. To enhance fodder production and conserve soil moisture C. setigerus grass was sown and trees seedlings of Acacia tortilis, Acacia senegal, Acacia nilotica, Butea monosperma, Zizyphus mauritiana, Pithecolobium dulce, Prosopis cineraria and Acacia leucopholoea were planted in July 2002 at 76 community pastureland covering 2545 ha area in Bhilwara district, Rajasthan. Reseeding of these pasturelands with C. setigerus alongwith plantation of tree seedlings under contour furrow/V-ditch soil and water conservation measures enhanced the productivity of these lands. Growth and biomass production of C. setigerus varied widely and followed the pattern of rainfall. Effect of soil depend upon suitability of conservation measures adopted, whereas interferences of livestock affected grass production negatively. Naturally growing tree, shrubs, herb and grasses added to increase carrying capacity of these pasturelands. Adoption silvipastoral activities enhanced fodder production and vegetation cover.

Abstract: Out of the three types of bamboo flowering, gregarious flowering results in ecological disaster and enormous loss to the bamboo resource. Based on observations and experience, certain indications to predict the occurrence of flowering has been put forward, however, the timing mechanism and behavioural trigger for the flowering remains an unexplained biological mystery despite various genetic and ecological hypotheses. For indigenous people who depend on bamboo for their livelihood, bamboo flowering foretells days of hardship. It is , therefore, essential to explore the way-out and formulate appropriate strategies to stagger the gregarious flowering so as to prevent the enormous loss of bamboo resource all at once. Staggerness in flowering of particular species can be achieved by idenfying cohorts having either similar flowering cycle but different temporal periods or having a different flowering cycle and raising plantations from seeds taken from different flowering cohorts. This would require precise assessment of bamboo resource, identification of flowering cohorts and proper management. Staggered bamboo flowering may offer several advantages from management point fo view so as to combat its ailing effects.

Abstract: Difference in growth performance between seed raised and clonally propagated plant materials, derived from nine 6-year old randomly selected female trees, grown in a clone bank of Casuarina equisetifolia L. was examined upto 3 years under controlled conditions. Half yearly observations on total height, collar diameter and data on shoot length, root length, collar diameter, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, biomass index and total biomass (fresh weight and dry weight basis) at the age of 3 were used for the study. The results of this early growth comparison clearly indicated the superiority of seedlings over rooted cuttings. This could be attributed to the fact that seeds were obtained as a result of random mating of the superior casuarina selections in the clone bank. Being a polygamous species, possibility of using clone bank as a research seed orchard exists in this species. Flowering and fruit setting were observed in clones from 8 months onwards. However, no flowering was noticed in any of the seedlings. As mature branchlet cuttings from higher up the stem can be rooted which will flower at a very early stage, clonal route will be the most promising option to raise orchards for quick and quality seed production in C. equisetifolia.

Abstract: Forestry CDM projects involving plantation of native species offer opportunity for CO2 mitigation by removal of accumulated CO2 in atmosphere and sequester it in vegetation, soil and wood products. Besides being grown for longer periods, tree species of medicinal importance are associated with recurring benefits to the growers, on account of fruits, seeds and other products. The present study on plantation of tree species of medicinal importance such as Amla, Arjun, Bael, Bahera, Harar, Jamun, Neem and Reetha on forest as well as the private lands have shown that there is significantly large sequestration potential in the range of 3.56 to 16.77 tons of CO2 per ha per year with corresponding carbon benefits of Rs 819/- to Rs 3,858/- and Rs 1,638/- to Rs 7,716/- under carbon prices of $5 and $10 per ton of CO2 respectively, on per ha per annum for a project period of 30 years. The study has further shown that the increase in return on account of carbon revenue is likely to motivate the small farmers to opt for plantation of these species on community lands and farm bunds.

Abstract: Groundnut cake (Kulikuli) samples were prepared with ginger (1.0% w/w) and without ginger. The effect of ginger, soaking for 30, 45 and 60 min and pulverizing treatments on the samples were evaluated for quality characteristics (microbial, proximate, functional and sensory properties). The ginger treated (GT) and 30 min soaked samples differed significantly (p=0.05) with lower (1.22 x 104 cfu g-1) total viable count (TVC) than the non-ginger treated (NGT) soaked samples (1.50 x 105cfu g-1). The same trend was observed for pulverized samples which had a TVC of 2.67 X 104cfu g-1 for GT and 2.80105cfu g-1 NGT. Pulverized samples irrespective of ginger treatment had higher TVC and fungal counts and differed significantly (p=0.05) from soaked samples. The most prevalent bacteria in the products were Staphylococcus aureus and Bacillus cereus while the fungal species included Aspergillus flavus, Penicillum digitatum and Geotrichum candidum. The pulverised GT had 42.16% protein while that of 30 min soaked sample reduced significantly (p=0.05) to 25.57% with further reduction to 17.28% at 60 min. The fat, fibre and ash contents followed similar trend. Longer soaking time increased the moisture and carbohydrate contents. Ginger treatment resulted in significant p=0.05 increase in water and oil absorption capacity of the product. The bulk density or gelling points of the products were not significantly different though a low level bulk density was observed. The taste , aroma and oveall acceptibility of GT sampels were more preferred than the NGT samples

Abstract: This study attempts to present a comprehensive discussion on potentially of production of lipase and catalase by fluorescent pseudomonads isolated from local red soil of the Acharya Nagarjuna University campus of the Guntur district, Andhra Pradesh. The isolates were identified to species level by morphological, physiological and biochemical characters as Pseudomonas aeruginosa, Pseudomonas aureofaciens, Pseudomonas putida and Pseudomonas fluorescens. Enzyme production by these fluorescent pseudomonads was assessed by inoculating the cultures into medium containing petroleum hydrocarbons viz., diesel and kerosene. Results indicated that all the isolates showed extracellular enzymatic activity when screened for production of lipase and catalase. The isolates were found to be more effective in utilization of petroleum hydrocarbons as sole source of carbon and energy and produced lipase and catalase at a significant level when compared with control (with out any hydrocarbon). THus these Pseudomonas isolates were found to be significant sources for the production of industrially important enzymes.

Abstract: Currently algae are being used in field and laboratory phytotoxicity tests for environmental monitoring and assessment of pollution. In this contest experiments were undertaken in laboratory condition to investigate the growth response of Spirulina to toxic heavy metals as the mechanism of tolerance, seems to be dependent on the metal involved. The algae were cultured in CFTRI medium enriched with different concentrations of metals for a period of 30 days. Growth index including total chlorophyll, protein content and glutathione -phytochelatin thiloic groups were estimated for each incubation period. Metal accumulation was estimated by AAS. Results indicated that supplementation of lower concentration of almost all metals was favorable for growth. Growth reduced significantly with higher concentrations of Hg, Ni and Cu. Among the metals Mercury was most toxic and the order of toxicity being Hg>Ni>cu>Zn>Fe. Zinc and Iron showed a growth promoting effect up to a concentration of 10 ?g/mL and 100 ?g/mL respectively showing a high tolerance. Hyper tolerance which made accumulation possible depends upon the mechanism to withstand metal induced stress with na increase in thiol production. Protein increased with low metal concentrations but decreased with high concentration. Little is known about the mineral concentration and metal uptake capacity in Spirulina, while such information has been demanded greatly in the assessment of algal food values.
